日本三菱电机公司最近推出的1,040×1,04象元(100万个象元)硅化伯(PtSi)肖特基势垒红外CCD焦平面列阵,这是迄今为止世界上出现的第一个集成度高达100万象元的红外焦平面阵列。由于象元的数目为旧有数目的4倍,因此图象质量更高,传感的角度也更宽。象元数目增加的原因,是将单元缩小了约一半,使100万个象元得以容纳于一块2cm见方的硅片上。这一点在以前很难办到,因为那样会降低温度分辨率。但是,现在 Japan’s Mitsubishi Electric recently introduced the 1,040 × 1,04-pixel (1-million-pixel) silicide (PtSi) Schottky barrier infrared CCD focal plane array, which is by far the world’s first integration Degree of up to 1 million pixel infrared focal plane array. Since the number of pixels is four times the old number, the image quality is higher and the sensing angle is wider. The reason for the increase in the number of pixels is to reduce the size of the cell by about half so that one million pixels can be accommodated on a 2 cm square silicon wafer. This is difficult to do in the past because that would lower the temperature resolution. but now
